Detailed Description

Rectangle with standard FLTK coordinates (X, Y, W, H).

This may be used internally, for overloaded widget constructors and other overloaded methods like fl_measure(), fl_text_extents(), fl_rect(), fl_rectf(), and maybe more.

Constructor & Destructor Documentation

Fl_Rect()

Fl_Rect::Fl_Rect ( int  X, int  Y, int  W, int  H, Fl_Boxtype  bt  )

inline

This constructor creates a rectangle with the given x,y coordinates and the given width and height reduced by the box frame size.

This is the same as using the constructor w/o bt and subsequently calling inset(bt).

Member Function Documentation

b()

int Fl_Rect::b ( ) const

inline

gets the bottom edge (y + h).

Note

r() and b() are coordinates outside the area of the rectangle.

inset() [1/3]

void Fl_Rect::inset ( Fl_Boxtype  bt )

inline

Move all edges in by the frame size of box type bt.

Shrinks the rectangle at all sides by the frame width or height of the given box type bt.

This method uses the frame sizes given by the box type bt using

• Fl::box_dx(bt)
• Fl::box_dy(bt)
• Fl::box_dw(bt)
• Fl::box_dh(bt)

If the rectangle is smaller than the frame sizes the result is undefined, i.e. an invalid or empty rectangle.

inset() [2/3]

void Fl_Rect::inset ( int  d )

inline

Move all edges in by d.

Shrinks the rectangle by d at all sides keeping the center of the rectangle at the same spot.

If d is negative, the rectangle is enlarged.

If d >= w() or h() the result is undefined, i.e. an invalid or empty rectangle.

inset() [3/3]

void Fl_Rect::inset ( int  left, int  top, int  right, int  bottom  )

inline

Move all edges in by left, top, right, bottom.

Shrinks the rectangle on all sides keeping the center of the rectangle at the same spot.

If any value is negative, the rectangle is enlarged.

Values are not range checked; it is possible to create an invalid or empty rectangle.

r()

int Fl_Rect::r ( ) const

inline

gets the right edge (x + w).

Note

r() and b() are coordinates outside the area of the rectangle.
